This new pre-print paper by Anthony Watts accomplishes so much. Assuming that no major problems are found, the pieces of the jigsaw fit and pass the common sense test. Yes, hot air rises off concrete. There goes half the warming trend. The most accurate thermometers in the right places are not recording high trends. High estimates come from combining good records with poor ones then adjusting that up. They show Muller and BEST’s latest exaggerated claims of 1.5C are meaningless. They show that only class 1 and 2 stations (which are placed well, not next to concrete, car-parks, or air-conditioners) give reliable data and the warming trend from these stations is much lower than the warming trend from Class 3, 4 or 5 stations. It’s what we always knew — thermometers near artificial heat sources are measuring artificial warming, but it’s not the global kind. Mueller, BEST, GISS, Hadley and all the others should have removed the data from poor stations entirely. No amount of statistical chicanery can correct the artificial warming effect no […]
